The workflow diagram starts by showing the proposal submission, which leads to proposal evaluation and contract development. The objective of a workflow context diagram is to focus attention on external factors and events that should be considered in developing a complete set of system requirements and constraints. As the image shows, the external actors surround the core system and can represent other systems as well as users. If the project team is having difficulty getting started, there are a variety of tools that can be leveraged to capture the list of actors. Create workflow context diagrams using EdrawMax or EdrawMax Online and share them among your peers in multiple formats.
